it looks like your solution *is* elegant... i tried
out your code, becuase i was astonished that such a
simple thing allegedly wasn't working... and it
did work.
below is the exact code i had in my text editor,
and it executed perfectly.
when i called $c->make(), it printed "A:: MAKE".
..am i misunderstanding your problem?
<?
class a {
function make() {
// some code
print "A:: MAKE";
}
}
class b extends a {
function make() {
// some code
parent::make();
}
}
class c extends b {
function make() {
// some code
parent::make();
}
}
$c = new c();
$c->make();
?>
